High-performance API design is crucial for handling large traffic, complex requests, and providing seamless user experiences. RESTful APIs are scalable, flexible, and simple, but can be cumbersome with complex resources. GraphQL allows clients to specify exact data needs, reducing latency and overhead, but requires a steeper learning curve. gRPC is high-performance and efficient, but requires significant investment in learning protobuf language and ecosystem.
RESTful APIs are based on client-server architecture, where clients send requests to servers, which respond with requested resources. Key concepts include resources identified by URIs, standard HTTP verbs for manipulation, and HTTP status codes indicating request outcomes.
